I think the problem with Mini is that the idea of getting the marque back into the WRC was stronger than the reality of it.
For instance, I saw this in my home town a few days ago, a Fiat Ritmo (I think it's sold elsewhere as a Fiat Bravo):

And I thought to myself "Hey, that would make a great little rally car! I wonder if Fiat would be interested?" (whether or not they actually would be interested is not the point, so please, bear with me for now). But I don't think that happened with Mini. I think someone thought to themselves "Hey, could we get Mini back into rallying? And if so, which car could we use?", which to my mind is doing things in the wrong order.
I think the Countryman was the wrong car for Mini to use. Like the Suzuki SX4 before it, it simply looks too big to be a rally car (although its not as bad as the SX4). I think it was the wrong car to use, and I'm not sure if there was ever a right car to use. I can't help but think that the decision to get Mini back into the WRC was made for the wrong reasons - for sentimentality, rather than because the car was good for competition.
